Synopsis

Description

reindexdb is a utility for
rebuilding indexes in a PostgreSQL database.

reindexdb is a wrapper around
the SQL command REINDEX. There is
no effective difference between reindexing databases via this
utility and via other methods for accessing the server.

Options

reindexdb accepts the
following command-line arguments:

-a--all

Reindex all databases.

[-d]
dbname[--dbname=]dbname

Specifies the name of the database to be reindexed. If
this is not specified and -a (or
--all) is not used, the database
name is read from the environment variable PGDATABASE. If that is not set, the user name
specified for the connection is used.

-e--echo

Echo the commands that reindexdb generates and sends to the
server.

-i index--index=index

Recreate index only.

-q--quiet

Do not display progress messages.

-s--system

Reindex database's system catalogs.

-t table--table=table

Reindex table only.

-V--version

Print the reindexdb
version and exit.

-?--help

Show help about reindexdb command line arguments, and
exit.

reindexdb also accepts the
following command-line arguments for connection parameters:

-h host--host=host

Specifies the host name of the machine on which the
server is running. If the value begins with a slash, it is
used as the directory for the Unix domain socket.

-p port--port=port

Specifies the TCP port or local Unix domain socket file
extension on which the server is listening for
connections.

-U username--username=username

User name to connect as.

-w--no-password

Never issue a password prompt. If the server requires
password authentication and a password is not available by
other means such as a .pgpass
file, the connection attempt will fail. This option can be
useful in batch jobs and scripts where no user is present
to enter a password.

-W--password

Force reindexdb to
prompt for a password before connecting to a database.

This option is never essential, since reindexdb will automatically prompt
for a password if the server demands password
authentication. However, reindexdb will waste a connection
attempt finding out that the server wants a password. In
some cases it is worth typing -W to
avoid the extra connection attempt.

Environment

PGDATABASEPGHOSTPGPORTPGUSER

Default connection parameters

This utility, like most other PostgreSQL utilities, also uses the
environment variables supported by libpq (see Section 31.13).

Diagnostics

In case of difficulty, see REINDEX and psql for
discussions of potential problems and error messages. The
database server must be running at the targeted host. Also, any
default connection settings and environment variables used by the
libpq front-end library will
apply.

Notes

reindexdb might need to
connect several times to the PostgreSQL server, asking for a password
each time. It is convenient to have a ~/.pgpass file in such cases. See Section 31.14 for more information.
